| 摘 要： | 在用分布式光度计测得灯具或光源的光强分布后，通常通过球带法来求出总光通量和／或局部光通量值，其本质是对定积分由求和来进行估算。由于球面坐标的特殊性，这种方法与在平面坐标系中的方法是有差别的。本文将分析这种差别，对此种计算方法的误差进行分析，并提出减少误差的改进方法。

| Abstract: | After getting the luminous intensity distributions of a lighting source by a goniophotometer system, the total and/or partial luminous flux are usually calculated by sphere-band method. Because of the particularity of spherical coordinate, this method is different from that of plane-coordinate system. The difference and calculation error of this method is analyzed and an improved method is proposed in this paper. |
